1. How to obtain niche oils? The extraction processes are often listed on the label: virgin, first press, cold-pressed or expeller-pressed. Only niche markets can absorb the processing costs, and production is limited compared to commodity oils such as canola, soybean or palm oils, which are consumed in millions of metric tons annually.The next two oils expected to move out of the specialty segment are sunflower and safflower oils. Sunflower oil, favored for high levels of polyunsaturates, now has improved oxidative stability through the development of high-oleic varieties. Oxidative stability of polyunsaturates increases when linoleic and linolenic fatty acids are replaced by the monounsaturate oleic acid.
2. What mean by interesterification? Interesterification is most widely practiced in the process of lauric fats and oils to make cocoa butter substitutes to improve the melting profile and reduce the melting point.It doesn't change the fatty acid content, it changes the triglyceride profile.Interesterification is widely used in Europe to increase the beta prime crystal formation in vegetable-oil-based margarines. This increases the stability and creaminess.
